The QDE* are a compensated flow control proportional valves, with pressure compensation and mounting surface according to ISO 6263-03 and ISO 4401-05, supplied with 2 or 3 way design, depending on the use of port P.

This valve is used for the regulation of the flow in branches of a hydraulic circuit or for the speed control of hydraulic cylinders.

The valve can be controlled directly from a current controlled power supply or with an integrated electronic, which allow to fully exploit the performance of the valve.

QDE* valves are available in two sizes, for 5 flow adjustment ranges of up to 80 l/min.

Pilot control can be internal, with intake of oil from line E, or external from a line with 1/4” BSP connection on the pilot body.

Drainage is always external and must be connected directly to the tank without backpressure by means of subplate connection Y (OR ø 35) or by means of a line (1/4” BSP coupling) on the pilot body.

The three-way version RPCE2-70-T3 allows flow control to the circuit by dumping the exceeding flow to the tank. Maximum pressure in the circuit is limited by means of a manual adjustment relief valve which operates on the compensator pilot.

RPCE2-70-T3 valve is also available in M version, which allows, by means of an electric control, to unload the total flow with a minimum pressure drop.

Pilot control can be internal, with intake of oil from line E, or external from a line with 1/4” BSP connection on the pilot body.

Drainage is always external and must be connected directly to the tank without backpressure by means of subplate connection Y (OR Ø32) or by means of a line (1/4” BSP coupling) on the pilot body.

The three-way version RPCE3-100-T3 allows flow control to the circuit by dumping the exceeding flow to the tank. Maximum pressure in the circuit is limited by means of a manual adjustment relief valve which operates on the compensator pilot.

The RPCE3-100-T3 proportional valve is also available in /M version, which allows, by means of an electric control, to unload the total flow with a minimum pressure drop.
